There are a growing number of evidence-based strategies to improve walking and walkability, but few of them have achieved wide use. Thus, there is a need to work toward improved dissemination and implementation for the most promising interventions. Leading researchers will provide an overview of the state of the science on effective walking and walkability interventions, specifically as it relates to D&I research. Important target populations, including racial, ethnic, and socioeconomic groups at highest risk for inactivity, will be discussed. Speakers will highlight interventions that have an evidence-base but have not been widely disseminated or implemented.
